  • Salinity (2007-2017)

    Salinity and Water Temperature Layer Picture The Salinity dataset is a culmination of year-round data from 2007-2017 from the Statewide Oyster Spat Monitoring (SOSM) Project sites and North Carolina Department of Marine Fisheries (DMF) collection stations. There is both a continuous raster layer that is used for a general pattern in salinity for the state, as well as the individual point layer that allows the user to click on each point to look further into the data from it. The legend color codes each site based on the average salinity in parts per thousand (ppt) and the ranking for most suitable salinity ranges for shellfish growth:

    • Red - 0.0-5.0 ppt and 40.1-45.0 ppt - salinity extremes, not ideal for shellfish growth
    • Orange - 5.1-10.0 ppt and 35.1-40.0 ppt - salinity extremes, not ideal for shellfish growth
    • Yellow - 10.1-15.0 ppt - low salinity, not ideal, but near the acceptable range for shellfish growth
    • Light Green - 15.1-20.0 ppt and 30.1-35.0 ppt - salinity within acceptable range for shellfish growth
    • Dark Green - 20.1-25.0 ppt and 25.1-30.0 ppt - salinity within acceptable range for shellfish growth

    Clicking on the site provides further information including average salinity, salinity minimum and maximum, average water temperature, water temperature minimum and maximum, average air temperature, air temperature minimum and maximum.

    - Conditionally Approved-Closed Areas (orange) - These areas are rarely opened to shellfish harvesting.
    - Conditionally Approved-Open Areas (green) - These areas are open to harvesting much of the year, but are immediately closed after certain rainfall events
